Multi lights Girls/Women's Shoes

These are a pair of girls/womens light up shoes. They have only been worn one time, and are still in perfect condition. They are older girls size 4, but I wear a women's size 7, and they fit perfectly. They have three different color of lights. You can do one color at a time, or there is a setting to have all colors going off at the same time. Does not come with charger. I am not sure how to charge them. I am asking $15.
